,GAS- BlURNER.

SPECIFICATION forming part of Letters Patent {1%. 654,944, datedJuly 31,1900.

Application filed April 2, 1906.

To all whom it may concern: T

Be it known that I, MICHAEL E. CARMODY," a citizen of the United States, and a resident or Zanesv11le, in the county of Muskingum and State of Ohio, have invented a new and Improved Gas-B urner, of which the following is a full, clear, and exact description.

This invention relates to improvements in sectional burners for gas employedas a fuel; and the object is to provide a simple burner in which the gas and air will be thoroughly mixed before reaching the point of comb'us tion and in which the gas-supply may be readily regulated.

I will describe a gas-burner embodying my invention and then point out the novel features in'the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in'all the figures.

Figure 1 is a perspective view of a burner embodying my invention. Fig. 2 is a section on the line w m of Fig. 1. Fig. 3 is a horizontal section, and Fig. 4 is a plan view, of a portion of the mixing-chamber.

Referring to the drawings, 1 designates a burner and mixing-tube divided by cross-partitions 2 3 into four chambers5, 6, 7, and 8. A portion of the tube 1 is enlarged," asfat 9, to form a portion of a mixing-chamber 10, the other portion of said mixing-chamber being provided with an enlarged portion 11 on a mixing-tube 12, having partitions 13," 14,15," and 16, which divide the mixing-tube into chambers which register with the chambers in the rear portion of tube 1. The parts 9 and 10 are suitably secured together, and arranged in the mixing-chamber is a'strainer 17, designed to thoroughly mix the air and gas passing through the same. By making an en larged mixing-chamber the gas and air will be caused to spread over a large area of strainer material, so that the samejwill not only be thoroughly mixed, but will first divide in a comparatively-small sheet.

Surrounding the tube 12 is a gas-receiver comprising a casing18, divided by partitions 19, 20, 21, and 22 into chambers 23, 24, 25, and 26. Within the casing 18 the tube 12 is provided with ports 2'7 for the passage of gas from the chamber 23 to the chamber between the Serial No. 1,177. (No an.)

partitions 13 and 14. Ports 28 provide communication between the chamber 24 and the chamber between the partitions 14 and 15. Ports 29 provide communication between the chamber 25 and the chamber between the partitions 15 and 16, while ports 30 provide communication between the chamber 26 and the chamber between the partitions 16 and 13.

'A gas-supply pipe 31 leads into one of the chambers, (here shown as the chamber 26,) and it is intended that the gas may be supplied'from one chamber, from two chambers, or from all the chambers, as may be desired. I prefer-ablyprovide the partitions 19, 20, and 21 eachwith a tube 32, providing communication Ifrom one chamber to another. The portion of each tube projecting intoa chamber is provided with an outlet or port 33,which has a valve-seat for a pin-valve 34, adjustable througha wallof the casing 18, as plainly indicated in Fig.1 3,'in'which the pin-valve is sh own as having its screw-threaded shank engaging in a tapped hole in the said wall of the casing. The air of course will be drawn into the front end of the tube 12.

In operation should it be desired to use a small amount of gas the valve in the tube 32 through the partition 19 is to be closed. Then the gas will pass from the chamber 26 through the ports SOand thence through the screen or strainer, where gas and air will be thoroughly mixed before passing to the point of combus- ;tion or to the inlet of the tube 1. there is a large volume of gas required, the several valves 34 are to be opened. Then of When course gas will pass into the several chambers 'ofthe' casing 18 and thence into the chambers formed in the tubes.

The advantage of this sectional burner is in the manipulation-that is, each section may be cut off and by so doing will prevent the combustion from flying back and taking place at a point near where the gas and air 5 come together. The device is durable, pra c' ticable, and economical for gas-fuel burners especially adapted for glass-houses, boilers, and other places where large volumes of gas are employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 7 1. A gas-burner, comprising an inlet-sec IOO tion divided Mintolongitudinal, chambers, an A outletsection divided into longitudinal charnbers and registering with the first-named chambers, a mixing-chamber between the two sections, a strainer in said mixing-chamber, and means for regulatingthe supplyoi gas to one or more of the chambers in the outletsecti'on of. the burner, substantially as speci fied. Y

2. A gas-burner, comprising an inlet-tube section, partitions longitudinally arranged in said tube-sectionand formi ng chambers, an: outlet-tube section also having partitionsp'ro; vidin g chambers communicating with the first-named chambers, the adjacent ends'of" the two. sections being enlarged to form a mixing=chamber,=a screen or spreader in said mixing-chamber, a gas=receiver attached to the outlet-section, and comprising-a casing divided into a series of chambers having communication with the chambers in the outletsection of the burner, and means for controlling asupply of gas to one or more of the chambers in the gas-receiver,substantially as specified. V

3. A gas burner, comprising an inlet-section divided into longitudinal chambers, an

outiet-section divided into longitudinalchambers communicating with the first named chambers, a. strainer or spreader arranged between the twosections,-a gas-receiver attached to the outlet-section of the burner and comprisin'ga easing, partitions in said casing dividiiig it into chambers having communication with the chambers in the "outlet-"section of the burner, tubes extended through certain of the partitions, valves for controlling the passage ofgas through said tubes, and a gas-supply pipie leading into one'of th'e chambers, substantially as specified.

4. A burner for fuel-gas, comprising an in.- let tubular section, divided into separate chambers, anputlet tubular section divided into separate chambers, the adjacent ends of the two sections being enlarged to form a gas-and air mixing chamber, a strainer or spreader in said enlarged portion, a gas-receiver surrounding the outlet-section, partitions in said gas-receiver, dividing it into common to all of the receiving-chambers, substantially as specified.

In testimony whereof "I have signed my name to this specification inth'e presence of twosubscribing witnesses. I
